実験手順
To a solution of methyl 3-chloro-2-oxo-1,2-dihydroquinoxaline-6-carboxylate (300 mg, 1.26 mmol) in DMSO (2 mL) was added DIEA (244 mg, 1.89 mmol), and (S)—N-methyl-1-phenylethanamine (204 mg, 1.51 mmol) with stirring for 3 h at 85° C. in an oil bath. The reaction was then quenched by the addition of water (50 mL). The product was precipitated via the addition of water and collected by filtration to give (S)-methyl 3-(methyl(1-phenylethyl)amino)-2-oxo-1,2-dihydroquinoxaline-6-carboxylate as a gray solid (323 mg, 76%).
